XO5083-013S

Overview

The MtronPTI XO5083-013S is a surface-mount Oven Controlled Crystal Oscillator (OCXO) designed for high-stability applications. It operates at a nominal frequency of 10 MHz with a standard 1x1 inch (25.4x25.4mm) footprint. The device utilizes a SC-cut crystal to ensure superior long-term stability and low aging rates compared to AT-cut alternatives. It provides a sine wave output, typically rated at +3 dBm, which facilitates direct interfacing with mixers or phase-locked loops without requiring additional amplification stages. The unit requires a 5V power supply and features a ceramic package suitable for automated assembly.

Feature Summary

• SC-cut crystal configuration ensures optimal thermal drift performance and superior long-term aging characteristics.
• Standardized 1x1 inch SMT footprint significantly reduces board space requirements compared to traditional through-hole OCXOs.
• +3 dBm sine wave output capability allows direct connection to RF components such as mixers and PLLs.

Applications

• Local oscillator source for portable short-range microwave radio systems
• Frequency reference for compact test and measurement instruments
• Synchronization clock for small base station infrastructure

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm the exact output type and crystal cut. The model designation indicates a sine wave output; however, other variants in the series may offer HCMOS outputs. Ensure that the PCB footprint matches the 1x1 inch ceramic package dimensions and that the design accounts for the required 5V supply voltage and thermal management via the ground pins.

Selection Notes

Select this component when high frequency stability is critical and space constraints prohibit the use of larger through-hole oscillators. The SC-cut variant is preferred over AT-cut for applications requiring minimal aging and tight temperature coefficients. Consider the +3 dBm output level to determine if external buffering is necessary for the specific load impedance of the downstream circuitry.

Part Context

This part belongs to the XO508x series of surface-mount OCXOs from MtronPTI. The series offers various configurations including different crystal cuts and output types. The XO5083 specifically denotes an SC-cut crystal with a sine wave output, distinguishing it from models like the XO5081 (AT-cut/sine) or XO5082 (AT-cut/HCMOS). This series targets applications demanding high reliability in a compact form factor.

Replacement Considerations

Direct replacements must match the 1x1 inch SMT footprint, 5V operation, and 10 MHz frequency. Verify that substitute parts provide comparable sine wave output levels and aging specifications. Cross-reference pinouts carefully, as pin numbering may not be silkscreened on the component body.

FAQ

What is the typical output power level for the sine wave signal?

The typical output power is +3 dBm, which is sufficient for driving mixers and phase-locked loops directly.

How does the SC-cut crystal affect performance compared to AT-cut?

The SC-cut crystal provides better long-term stability and lower aging rates, making it suitable for high-precision synchronization applications.
